Adjustable fan and post mount

ABSTRACT

An electric or battery powered fan has Omni-Directional adjustments which include a Single point keyhole Oscillation system that adapts a male end (key) flexible pipe coupled to a female keyhole detent system which is coupled to a spring push pin mechanism which allows for angle adjustments at a specific coefficient of friction, which are adjusted by torque from detent and stop mechanism. The flexible pipe allows for unlimited directional adjustments that withstand repositioning at any direction. Said flexible pipe rotates 360 degrees inside the clamp in both directions on a rotational axis. The clamp design which is a quick release mechanism based on the radius of clamp jaw and lag bolt which allows for a quick release mounting system. It is therefore possible to direct air-flow in infinite variations.

As will be appreciated by those skilled in the art, fans for providing air movement are known in the ventilation art and have been available for some time More recently, powered personal fans have become increasingly popular. Also, portable fans for providing temporary ventilation of small areas have become increasingly popular as well. Patents disclosing information relevant to the present invention include U.S. Pat. Nos. 7,320,450, 7,011,279, 5,435,696, 5,720,594, 5,370,500, 5,737,847, 4,732,539, 4,850,804, and 4,461,439. The teachings of each of these patents are hereby expressly incorporated by reference in their entirety.

U.S. Pat. No. 7,320,450 shows a configurable mounting apparatus. A multiply configurable mounting apparatus having an elongated permanently bendable support leg with a support base coupled to a first end of the support leg, the support base being structured for securing the mounting apparatus relative to an external surface; and a mounting platform coupled to a second end of the support leg opposite from the first end, the mounting platform is structured for mounting an external device to the second end portion of the permanently bendable support leg.

U.S. Pat. No. 7,011,279 shows a support device with flexible support arm. In a support device with a flexible support arm including a mounting structure for mounting the support device to a base, a support structure for engaging an article and a flexible support arm extending provided, each having its own oscillation motor and each being selectively operable independent of the other. Optionally, the main fan motor may be employed to power one oscillation mechanism. The fan has a base for desk top support, or a base and extensible column for floor support, or a bracket for permanent mounting. All embodiments have controls for controlling the fan motor and the oscillation motor or motors, and a limited tilting feature for maintaining the fan blade at an angle to the base or bracket.

U.S. Pat. No. 5,370,500 shows a fan support for supporting a fan in an elevated position and oscillating the fan about the support. The device includes an adjustable column supported in a vertical position by a plurality of legs. A fan support channel is pivotally mounted to a top end of the column and is operable to receive and support a fan, such as a box shaped fan, thereon. An oscillation device is provided to effect a repetitive pivoting movement of the support channel in the horizontal plane, and a thermostat for controlling operation of both the fan and the oscillation device is also included.

U.S. Pat. No. 5,737,847 shows a telescoping stand with pivotable holder for a hand-held hair dryer including a stand having a base and a manually and telescopically adjustable pole extending therefrom and terminated at a free end; and a coupling mechanism secured to the free end of the pole for removably holding a hand-held hair dryer and allowing it to be positioned at different angles for use.

U.S. Pat. No. 4,732,539 shows an oscillating electric fan having a neck joint which is mounted for tilting movement back and forth on the top of an upwardly projecting portion of a base and a fan unit mounted on top of the neck joint for oscillating movement on the neck joint about a vertical axis includes a flexible clip element which serves to selectively limit the extend of the tilting movement of the neck joint. The clip element, which is attached to the bottom of between the mounting structure and the support structure, the support arm comprises a non-elastic flexible metal rod having a polygonal cross-section with opposite ends on which end sleeves with corresponding polygonal axial openings are mounted so as to be snugly connected to the ends of the polygonal metal rod in a rotationally form-locking manner while the end sleeves are firmly mounted in sockets formed on the mounting and support structures of the support device.

U.S. Pat. No. 5,435,696 shows a tillable oscillating fan assembly for use in circulating air. In one embodiment, the fan assembly includes a stand, a fan head and a neck joint. The top of the stand terminates in upwardly extending bifurcated portions. The fan head is rotatably supported on the neck joint. The bottom of the neck joint is shaped to include a rounded portion which is pivotally mounted between the bifurcated portions of the stand. One side of the rounded portion is shaped to include a recessed arc which extends over an angular distance of approximately 90 degrees. An angular boss mounted on the inside surface of one of the bifurcated portions limits the angular movement of the rounded portion relative to the bifurcated portions by abutting the neck joint at opposite ends of the recessed arc. When the boss abuts the neck joint at one end of the recessed arc, the fan head is positioned vertically. When the boss abuts the neck joint the opposite end of the arc, the fan head is positioned horizontally. To secure the fan head at the aforementioned horizontal and vertical positions and at a plurality of positions therebetween, the fan assembly also includes a locking screw which is insertable through the mounting post and the boss and which is used to frictionally engage the arc at a desired position.

U.S. Pat. No. 5,720,594 shows a portable fan providing oscillation in two axes. Oscillation may occur simultaneously in two axes, or in one selected axis. Two oscillation mechanisms are the neck joint has a hooked shaped tip which will strike the front wall of the upwardly projecting portion of the base when the neck joint is tilted down about 20 degrees from the horizontal axis and as a result prevents further downward tilting movement. However, by manually flexing the clip element upward away from the front wall the neck joint can be tilted further downward so as to place the fan in a collapsed or folded position.

U.S. Pat. No. 4,850,804 shows an electric fan has a universally adjustable mounting which includes a vertical stem rotatable in a pedestal, and a pair of support joints extending above the stem and pivotal in mutually perpendicular planes. It is therefore possible to position the fan in lateral displacement from the stem, such that its back thrust creates a torque force tending to rotate the stem. The stem at its lower end has a base plate parallel to the pedestal. A pair of ball-and-spring mechanisms located between the base plate and pedestal permit the stem to be manually rotated to a selected position of adjustment where the balls engage a corresponding pair of holes. Yet the spring strength is sufficient to resist the torque produced by operation of the fan.

U.S. Pat. No. 4,461,439 shows a two-part holder for an appliance, such as a manually operable hairdryer, includes a stationary wall mounted bracket as one part and a relatively movable appliance clamping portion as the other part. The clamping portion may be clamped about an appliance and quickly connected to and quickly removed from the stationary bracket without manipulating any fastening mechanism. An abutment projecting from the bracket retains the electric supply cord of an appliance out of the user's way.

Thus, it may be seen that these prior art patents are very limited in their teaching and utilization, and an improved adjustable Stand and post mount is needed to overcome these limitations. What is needed then is an improved mechanism for mounting an oscillating fan that may be mounted to existing structures and particularly vertically oriented structures such as the post on a music stand or musician's instrument stand or the like. It is also desirable that the fan orientation be easily adjustable by the user during operation and particularly without requiring the user to interrupt other activities to adjust the fan orientation.
